Our team of inspectors reduce the risk of contamination of the public water supply from backflow of any fluid. Fluids are risk categorised from Fluid Category 1 to Fluid Category 5 with the following definitions provided:
- Fluid category 1: Wholesome (mains) water.
- Fluid category 2: Fluid 1 whose aesthetic quality is impaired due to a change in its temperature, or presence of substances or organisms causing a change in taste, odour or appearance.
- Fluid category 3: Fluid represents a slight health hazard because of the concentration of substances of low toxicity, e.g. containing ethylene glycol or common disinfectants.
- Fluid category 4: Fluid represents a significant health hazard due to the concentration of toxic substances, including any fluid containing chemical, carcinogenic substances or pesticides or environmental organisms of potential health significance.
- Fluid category 5: Fluid represents serious health hazard due to the concentration of pathogenic organisms, radioactive or very toxic substances, e.g. containing faecal material or other human waste; butchery or other animal waste or pathogens.
